Features:

• 7 x 9V DC outputs on a common ground (not isolated)
• 3 x 18V DC outputs on a common ground (not isolated)
• 375mA total current available on 9V outputs
• 625mA total current available on 18V outputs
• Plug-top/wall wart and pedal board distributor style design

Advantages over the Diago Powerstation:

• 18V built in; doesn't require an extra device to make 18V
• High current avaliable on the 18V outputs

Disadvantages with respect to the Diago Powerstation:

• Still requires a wall wart style power supply, never shown on photographs!
• Doesn't have a great deal of current available for standard 9V DC pedals. Easily overloaded
• Known to cause 'thudding' noises when near it's current limit
• If not used on the pedal board, the thin output lead becomes prone to damage on the floor
• Known to have 'whining' clock frequency clashing problems with some delay pedals
• Will technically work in any country, but requires the correct plug adaptor
